Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical disintegration of garden waste, and in particular relates to a shearing type shredder. Background Art

[0002] The shredder can effectively shred large materials into small ones. It has the characteristics of strong power, high stability, low loss and low noise, and is widely used in waste collection and transportation, treatment and disposal pre-processes, etc. However, the mainstream shredder uses the shredding method of cutting teeth to squeeze the material to break and separate it, which is not effective in processing slender, thin and soft materials, hindering the application and promotion of shredders, especially in the treatment of garden waste. There is still a technical gap.

[0003] Therefore, developing a shredder that can shred slender, thin and soft materials can better expand its scope of application and is very necessary to solve the pain points of garden waste treatment. Summary of the invention

[0004] The utility model aims to provide a shearing type shredder to solve the problem of poor shredding effect proposed in the above background technology.

[0005] The purpose of the utility model and the technical problem to be solved are achieved by adopting the following technical solutions. According to the utility model, a shearing shredder is proposed, which includes a frame 1, a driving shaft 2, a driven shaft 3, a driving device 4, a main blade 5, a secondary blade 6, a driving gear 7, a driven gear 8, an adjusting device 9, a partition 10, and a reinforcing support 11; the driving shaft 2 and the driven shaft 3 are respectively mounted on the frame 1; the main blade 5 and the secondary blade 6 are staggered in pairs on the driving shaft 2 and the driven shaft 3, and the total number is not less than 6; the driving gear 7 is mounted on the driving shaft 2; the driven gear 8 is mounted on the driven shaft 3 and meshes with the driving gear 7; the driving device 4 is mounted on the frame 1, and the output shaft of the driving device 4 is connected to the driving shaft 2.

[0006] The main blade 5 also includes a blade 51, and the blades 51 are evenly distributed around the main blade 5, and the number of the blades 51 is not less than 3. The auxiliary blade 6 also includes a cutting groove 61; the cutting grooves 61 are evenly distributed around the auxiliary blade 6, and the number of the cutting grooves 61 is equal to the number of the blades 51; the driving device is an electric motor or a hydraulic motor.

[0007] The purpose of the utility model and the solution to its technical problems can be further achieved by adopting the following technical measures:

[0008] Preferably, the adjusting device 9 is respectively installed on the driving shaft 2 and connected to the driving gear 7 and on the driven shaft 3 and connected to the driven gear 8 .

[0009] Preferably, the partition is installed on the frame 1.

[0010] Preferably, the reinforcing support 11 is mounted on the frame 1 and is slidably connected to the driving shaft 2 and the driven shaft 3 respectively.

[0011] Compared with the prior art, the utility model has the following beneficial effects: conventional shredders tear materials only when the tip of each tooth rotates to tangent with the outer circle of the circular spacer sleeve. Compared with conventional shredders, the circular spacer sleeve is replaced with a concave arc blade for the auxiliary blade 6. When the two shafts rotate in opposite directions, the tip of the main blade 5 brings the material into the concave arc of the auxiliary blade 6, and the tip of the main blade 5 moves along the inner arc of the concave arc of the auxiliary blade 6 to tear the material. The solution of the utility model changes the point contact between the main blade 5 and the auxiliary blade 6 to line contact, and the shredding effect is better.

[0012] The above description is only an overview of the technical solution of the utility model. In order to more clearly understand the technical means of the utility model, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the utility model more obvious and easy to understand, the following preferred embodiments are specifically cited and described in detail with the accompanying drawings.
